HTML markup errors and warnings
(Rescan now...)
Warnings:
The “banner” role is unnecessary for element “header”.
The “navigation” role is unnecessary for element “nav”.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “contentinfo” role is unnecessary for element “footer”.
Errors:
Bad character “<” after “<”. Probable cause: Unescaped “<”. Try escaping it as “<”.
Attribute “pubdate” not allowed on element “time” at this point.
No “p” element in scope but a “p” end tag seen.
The “center” element is obsolete. Use CSS instead.
A slash was not immediately followed by “>”.
The “align” attribute on the “img” element is obsolete. Use CSS instead.
Stray end tag “aside”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
End tag “footer” seen, but there were open elements.
Unclosed element “div”.
